WATER-HEATER.

Specification of Letters Patent. Patented Sept, 14, 1915,

Application filed. November 16, 1914. Serial No. 872,434.

T all whom it may concern:

Be it known that I, DAVID HAMILTON, a citizen of the United States,residing at Greensburg, in the county of Westmoreland and State ofPennsylvania, have invented certain new and useful Improvements inWVater-Heaters; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to improvements in water heaters and has for itsobject to provide an extremely simple device of this character which maybe employed for quickly and effectively heating water to be conveyed toa number of radiators or to hot water spigots in a building. In carryingout the above object, I employ the construction hereinafter describedand claimed and shown in the drawings wherein:

Figure 1 is a front elevation of a heater constructed in accordance withmy invention; Fig. 2 is a central vertical longitudinal section as seenon the line 2-2 of Fig. 1; Fig. 3 is a central transverse section takenon the line 3-3 of Fig. 2; and Fig. 4 is a longitudinal section as seenon the plane of the line 4-4 of Fig. 2.

In the accompanying drawings forming a part of this application, thenumeral 1 designates the lowermost of a plurality of hollow waterheating sections, 2 the uppermost of these sections, and 3 theintermediate sections. The section 1 comprises a flat hollow rectangularbody 4 and a hollow U-shaped spacing wall 5 which rises from three edgesof the body 4 and communicates with the in terior of said body as shownin the various figures of the drawings. The two parallel side edges ofthe body 4 are equipped with the parallel arms 6 of the U-shaped wall,while the connecting portion 7 thereof rises from the rear edge of saidbody 4, said portion 7 being provided with a transversely elongatednotch 8 at its upper edge.

By reference more particularly to Fig. 3, it will be seen that a pair ofopenings 9 having tapered walls are provided in the two arms 6, of thewall 5, said openings receiving the lower ends of barrel-shaped nipples10 which depend from the bottom of the adjacent intermediate section 3,said bottom also having tapered openings which receive the upper ends ofthe nipples as shown. The lowermost section 3 as well as the otherintermediate sections, are identical in construction with the section 1,with the exce tion that they-are provided with openings 9 in theirbottoms as well as in the upper edges of their U-shaped walls 5. Byreference to the various figures, it will be seen that the intermediatesections rest one upon the other with nipples 10 projecting into theopenings 9 of adjacent sections, whereby water tight joints areprovided.

The uppermost section 2 comprises a hollow rectangular body 4 which isprovided with a pair of tapered openings 9 from which two nipples dependinto the openings 9 of the uppermost intermediate section 3, as shown.With the parts in this position, four upright bolts 20 are passedthrough cars 20 on the lower section 1 and through similar ears on theupper section 2, said bolts receiving nuts 21 on their upper ends,whereby all of the sections may be held in fixed relation.

Secured to the rear side of the heater thus formed, and having aplurality of slots 25 registering with the notches 8 of the varioussections, is an upright flue 26 whose upper end is provided with anannular flange 27 for the connection of a suitable draft pipe.

Rising from the uppermost section 2, is a pair of outlet pipes 30through which heated water is discharged, this water being preferablypassed through the radiators and re turned to the lowermost section 1through a return pipe 31 and a second return pipe 31, the latter beingconnected by a T coupling 35 with a water inlet pipe 36 which may leadfrom any appropriate source of supply, and may, if desired, be providedwith a suitable valve (not shown).

Spaced laterally from the heater and slightly in advance thereof, is anupright gas supply pipe 40 from which a plurality of horizontal pipes 41project laterally in front of the various sections of the heater, thesepipes 41 being provided with cut-off valves 42 and supporting aplurality of double burners 43 which project into the spaces between thevarious sections and which are, therefore, partially surrounded by theU- shaped hollow walls above described. For the purpose of effectivelylighting the burners 43, a plurality of valved pilot lights 45 areemployed, said lights being fed by a pipe 46 which branches from thepipe 40 as shown.

I may here explain that I am aware that various forms of Water heatershave heretofore been placed on the market, but I am not aware that aheater of the class set forth inthe claim, has heretofore existed. Itwill be understood that a device of this character will be extremelyefficient since heat radiating in all directions from the burners 43 isutilized, either by contact with the bottom and top walls of the varioussections or with the U-shaped Walls thereof. 7

From the foregoing description, taken in connection with theaccompanying drawings, it Will be seen that a very simple heater hasbeen provided, yet one which will effectively perform the functions forwhich it is designed.

I claim: I

A water heater comprising a fiat hollow water 'heatin g section, aU-shaped hollow wall formed integrally with said section, rising fromthe edge thereof, and communicating throughout its length therewith,said wall Copies of this patent may be obtained for five cents each, byaddressing the Commissioner of Patents,

upper side thereof, a burnerinterposed between the two sections andpartially surrounded by the hollow wall, an inlet into the 1 firstsection, and an outlet from'th'e other section, the transversedepression facilitating the discharge of gases from the burner.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. I g V 1 DAVID HAMILTON.
